This and the "war on terror" are perfect examples of not creating actionable, measurable goals for an initiative. The equivalent of this in business strategy are projects with goals like, "Make the best iPhone App ever" and "Make the company more social".
How do you know when to stop? How do you know when you're done?
I think it's more of a continuum than that:
Let's make the best program ever
Let's make a great calendar
Let's make a calendar that makes it easy to share files
Let's make a calendar with ftp
How do you know when to stop? How do you know when you're done?
